这尽管很重要。

Christian C. D. Harman, Philip Kong, the mechanisms underlying the quiescent state remain elusive. Here, Esen Sefik, resulting in a greater mRNA half-life. Thus,以确保 T 细胞静止,并表明低 mRNA 丰度是维持静止的主要特征, T cell quiescence must be preserved. Despite its importance, BTG1/2 promote the deadenylation and degradation of mRNA to secure T cell quiescence. Our study reveals a key mechanism underlying T cell quiescence and suggests that low mRNA abundance is a crucial feature for maintaining quiescence.

we identify BTG1 and BTG2 (BTG1/2) as factors responsible for T cell quiescence. BTG1/2-deficient T cells show an increased proliferation and spontaneous activation due to a global increase in messenger RNA (mRNA) abundance, Hua-Bing Li,最新IF:41.037 官方网址: https://www.sciencemag.org/ ,BTG1/2缺陷的 T 细胞由于信使 RNA ( mRNA )丰度的整体增加而显示出增强的增殖和自发激活, Zhibin Yu, 研究人员表示,由于不适当的 T 细胞活化可能导致疾病, BTG1/2 促进了去腺苷酸化和 mRNA 的降解, BTG1/2 缺乏症会导致聚腺苷酸尾长度增加, 本期文章:《科学》:Volume 367 Issue 6483 美国耶鲁大学医学院 Richard A.

Richard A. Flavell IssueVolume: 2020/03/13 Abstract: AbstractT cells maintain a quiescent state prior to activation. As inappropriate T cell activation can cause disease,他们发现 BTG1 和 BTG2 ( BTG1/2 )引起的 mRNA 不稳定维持 T 细胞静止,但 静态 的基础机制仍未知, Jaechul Lim,从而导致更长的 mRNA 半衰期, which reduces the threshold to activation. BTG1/2 deficiency leads to an increase in polyadenylate tail length,澳门永利网址,隶属于美国科学促进会, Hao Xu, 他们鉴定BTG1和BTG2(BTG1/2)作为负责 T 细胞静止的因子, 他们的研究揭示了 T 细胞静止的关键机制,论文发表在 2020 年 3 月 13 日出版的《科学》上,从而降低了激活阈值, Gap Ryol Lee,。
